Maintain your HS29-261-3 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The HS29-261-3 is a two-and-a-half-ton 240V single-phase R-22 residential outdoor condensing unit using R-22 refrigerant. The HS29-261 designation identifies a Lennox HS29 series unit with a 240V single-phase power configuration distinct from the standard 208/230V configurations. The HS29-261-3 is revision 3 of this configuration. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Lennox OEM parts for the HS29-261-3 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

HS29-261-3: Two-And-A-Half-Ton 240V Single-Phase R-22 Outdoor Condensing Unit Service
Annual capacitance testing of the dual run capacitor before the cooling season is the most cost-effective preventive maintenance step for the HS29-261-3. Match all microfarad values from the installed capacitor label before ordering a replacement. The central air conditioner repair help section covers capacitor testing and contactor diagnosis for this platform.
Most Replaced Parts on the HS29-261-3
Dual Run Capacitor for the HS29-261-3
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor. A reading more than 10% below the rated value causes the compressor to hard-start. Match all three microfarad values from the installed capacitor label before ordering.
HS29-261-3 Contactor
The contactor closes the 240-volt compressor circuit at every cooling cycle start. Pitted or burned contacts generate heat that transfers to the compressor motor terminals. Replace a contactor with visibly eroded contacts before compressor winding damage occurs.
Outdoor Fan Motor for the HS29-261-3
The outdoor fan motor pulls air through the condenser coil. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
High-Pressure Switch for the HS29-261-3
A high-pressure switch that trips repeatedly under normal ambient conditions points to a blocked condenser coil, failed fan motor, or refrigerant overcharge rather than a failed switch diaphragm.

HS29-261-3 Parts FAQ
What is the HS29-261-3 and what ton size is it?
The HS29-261-3 is a two-and-a-half-ton 240V single-phase R-22 residential outdoor condensing unit using R-22 refrigerant. The HS29-261 designation identifies a Lennox HS29 series unit with a 240V single-phase power configuration distinct from the standard 208/230V configurations. The HS29-261-3 is revision 3 of this configuration.
Why does my HS29-261-3 hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor. Test the capacitor with a digital capacitance meter before testing any other component.
How does the Lennox HS29-261-3 differ from the standard HS29-030 configurations?
The HS29-261-3 uses a 261-series power configuration distinct from the standard HS29-030 model designations at the same approximate capacity. Always confirm the full model designation from the unit data plate before ordering a replacement capacitor or control board.
How often should I test the capacitor on the HS29-261-3?
Test the capacitor annually before the cooling season. A reading more than 10% below the rated microfarad value indicates a weakening capacitor that should be replaced before it fails under peak summer load.
